VW TDI berth air & ammunition clarify replacement

!: VW TDI berth air & ammunition clarify replacement

Replacing the cabin air filter and fuel filter in my 1997 Volkswagen Passat TDI diesel... or at least trying to. It seems I got a defective fuel filter. No amount of priming and purging the fuel lines could get the engine started and running with the new fuel filter; it must've had an air leak somewhere. I reinstalled the old filter and within a few cranks the engine was purring like a kitten. I noticed the new one was made in Spain instead of Germany, so maybe even MANN is cheapening out these days... Anyway, the instructions I give are valid for any Mk3 Golf/Jetta, B4 Passat, or pre-2004 Mk4 Golf/Jetta TDI diesel. Older non-TDI diesels are similar as well, although diesels prior to 1989 do not have the thermostatic valve (held in by the clip) and extra fuel lines which cycle fuel through the injection pump and back into the fuel tank in cold weather to help keep the fuel from gelling. Also not all Mk3s came from the factory with a cabin air filter, although you can buy the housing to retrofit one into your car if it doesn't have it.
